Beyond body mass index (BMI) : The role of diabetes and central obesity in fracture risk—Insights from the UK biobank

Diabetes Obes MetabPublished Prospective cohort study

Authors' conclusion

Although a higher BMI appears protective, central obesity and diabetes are important contributors to increased fracture risk in individuals with obesity. These findings emphasize that, beyond maintaining a healthy weight, clinicians should assess central obesity and diabetes to better identify those at high fracture risk.

Study context

Population
UK Biobank participantsUK Biobank
Participants
446,219 participants
Exposure
BMI categories and tertiles of waist circumference (WC) and waist-to-height ratio (WHtR)
Outcome
Fracture incidence
Methodological detailsmultivariable Cox models, stratified by diabetes status
  • Multivariable Cox models
  • Stratified by diabetes status

Main finding

As reported in the abstract

Fracture
Each group vs normal weightAdjusted hazard ratio (95% CI)
Overweight
0.79(0.76–0.82)
Obesity
0.73(0.70–0.77)

Observational data: associations, not effects.

Further findings

Fracture by WC and WHtR

Higher WC and WHtR generally associated with lower fracture risk; U-shaped pattern observed

Fracture with higher WC, within overweight and obesity

Higher WC, overweight: aHR
1.12 (1.05-1.20) (95% CI)
Higher WC, obesity: aHR
1.23 (1.12-1.35) (95% CI)

Fracture by diabetes status

DM independently associated with higher fracture risk across all BMI categories, further elevated with central obesity
